Definitions

  • the present invention relates to topical products with a biphasic system, as well as to a method for preparing the same.
  • Trichloroacetic acid glycolic acid, resorcinol, salicylic acid, pyruvic acid, phenol, mandelic acid, lactic acid, retinoic acid, kojic acid, citric acid, pyruvic acid etc.
  • the action of these treatments depends on the type of acid used, the concentration and chemical stability thereof and also the area of application.
  • Trichloroacetic acid is one of the most widely used substances owing to its marked exfoliating properties.
  • Trichloroacetic acid has a structure comparable to that of acetic acid to which the three hydrogen atoms have been substituted with three chlorine atoms. This substitution shifts the electronic charge of the "alpha" carbon towards the chlorine atoms, thus determining a condition of partial electron-deficiency on the above- mentioned carbon, which in turn attracts the electronic charge of the adjacent carbon and therefore of the oxygen, which will tend to divide the proton more significantly if introduced into an aqueous environment, owing to the marked derealization of the negative charge.
  • the oxidation of trichloroacetic acid is known in the medical field, as it involves the browning of the products containing the same, normally used in the form of monophasic hydro gels, with a relative cleavage of the trichloroacetic acid molecule.
  • the browning of the compound in addition to the loss of activity of the product, also entails a very significant loss of safety of the product containing trichloroacetic acid, since the latter will no longer contain the trichloroacetic acid as such, but a mixture of trichloroacetic acid, chloroform and formic acid. The mixture will tend to be composed of the latter as the oxidative process completes until the total trichloroacetic acid contained in the product is split.
  • WO2007/042824A1 describes a composition comprising trichloroacetic acid, alpha-, beta- and polyhydroxy acids, vitamins, amino acids.
  • Said composition is an emulsion with an oil phase consisting of polysiloxanes, silicones, mineral oils or essential oils.
  • US2009/0117068 describes a solid composition applicable to a razor.
  • Said composition comprises hydroxy acids, polyhydroxy acids, trichloroacetic acid.
  • said cosmetic compositions do not provide a protection for the trichloroacetic acid which, upon contact with oxygen, can oxidize and modify its nature.
  • Another drawback is due to the fact that there is not a system which allows the use of the topical composition in complete safety even after opening a package which contains the same.
  • US2014/037561 describes compositions comprising trichloroacetic acid, which is stabilized with a mixture of chemical stabilizing agents in ratios from 0.1: 1 to 5: 1.
  • Example 5 it is stated that under the same conditions, after 90 days, while the TCA in aqueous solution alone degrades by 12.6%, when it is in the presence of a low percentage of stabilizing agents, it degrades on average by 4-5%, and when it is in the presence of a high percentage of stabilizing agents, it degrades on average by 2-3%. Therefore, the teaching is to increase the amount of chemical stabilizing agents with respect to the TCA, however without providing information about the trend of this degradation over 90 days, and certainly without having considered the impact on the tolerability of the composition on the skin.
  • the object of the present invention is therefore to obtain products for medical use, in particular for topical use, capable of maintaining constant over time the properties of all the components present in the products.
  • Another object is to obtain topical products capable of preserving the nature of trichloroacetic acid.
  • the present invention relates to a method for preparing topical products capable of preserving the nature of trichloroacetic acid and preventing oxidation thereof, as described in claim 22.
  • the invention therefore relates to a biphasic topical product comprising a mixture of hydroxy acids, trichloroacetic acid and bioactive substances with non-exfoliating activity, wherein two phases are present, a hydrophilic phase and a lipophilic phase. Said lipophilic phase floats above the hydrophilic phase, so that the latter does not come into direct contact with the oxygen present in the atmosphere.
  • the biphasic product of the present invention has and maintains a clear-cut separation surface between the two phases immiscible with each other, since the product is free of emulsifying surfactants.
  • the lipophilic phase overlying the hydrophilic phase wherein trichloroacetic acid (or TCA) is present, creates a physical barrier which isolates the hydrophilic phase, thus preventing the contact with the air and therefore, as said, with oxygen causing the oxidation of TCA.
  • TCA trichloroacetic acid
  • TCA as well as the entire hydrophilic phase as a whole, is conserved for very long periods of time, even for a few years, without significant variations and above all without the use of stabilizers or chemical preservatives.
  • the solution provided by the present invention is therefore particularly advantageous in that it allows eliminating the use of stabilizers and chemical preservatives without compromising the stability of the product, on the contrary obtaining a long and constant preservation capacity over time.
  • the biphasic product of the present invention is therefore both highly tolerable by the skin, even in the case of subjects exposed to allergies, and extremely stable, as well as visually pleasing and commercially attractive.
  • the biphasic topical product of the invention therefore comprises a mixture of hydroxy acids, trichloroacetic acid and bioactive substances with non-exfoliating activity, wherein said topical product comprises a hydrophilic phase and a lipophilic phase, the biphasic topical product being free of emulsifying surfactants, and said bioactive substances with non- exfoliating activity comprise a mixture of vitamins and amino acids.
  • the biphasic topical product is also free of stabilizers and preservatives.
  • This mixture of hydroxy acids, trichloroacetic acid and bioactive substances is present in the hydrophilic phase.
  • Said hydroxy acids may be alpha-hydroxy acids, beta-hydroxy acids, or polyhydroxy acids.
  • the alpha hydroxy acids are for example selected from tartaric acid, citric acid, glycolic acid, lactic acid, malic acid; the beta hydroxy acids are for example selected from hydroxybutyric acid and salicylic acid; the polyhydroxy acids are for example selected from lactobionic acid and gluconolactone.
  • the hydrophilic phase preferably comprises tartaric acid, citric acid, salicylic acid and lactobionic acid.
  • Tartaric acid is present in a final concentration of 2% to 15%, preferably 3% to 12%, even more preferably 4% to 10%.
  • “%” means “% by weight” based on the weight of the phase wherein the ingredient is present.
  • Citric acid is present in a final concentration by weight of 0.3% to 5%, preferably 0.4% to 4%, even more preferably 0.5% to 3%.
  • Salicylic acid is present in a final concentration by weight of 0.5% to 14%, preferably 0.75% to 12%, even more preferably 1% to 10%.
  • Lactobionic acid is present in a final concentration by weight of 3% to 10%, preferably 4% to 13%, even more preferably 5% to 11%.
  • Trichloroacetic acid has a final concentration by weight of 5% to 60%, preferably 7% to 55%, even more preferably 9% to 50%.
  • amino acids present in the hydrophilic phase are for example glycine, proline, hydroxy-proline and arginine. Said amino acids have a final concentration by weight of 0.01% to 12%, preferably 0.02% to 10%, even more preferably 0.03% to 10%.
  • the vitamins present in the hydrophilic phase have a final concentration by weight of 0.05% to 2%, preferably 0.06% to 1.5%, even more preferably 0.07% to 1%.
  • the vitamins present in the hydrophilic phase are riboflavin (Vitamin B2) and Vitamin C.
  • the hydrophilic phase also comprises gamma-amino-butyric acid (GABA) or dimethylaminoethanol with a contracturant and muscle relaxant action.
  • GABA gamma-amino-butyric acid
  • dimethylaminoethanol with a contracturant and muscle relaxant action.
  • GABA is present in a final concentration of 1% to 10%, preferably 2% to 8%, even more preferably 3% to 7%.
  • Dimethylaminoethanol is present in a final concentration by weight of between 0.1% and 1%, preferably between 0.2% and 0.8%, even more preferably between 0.3% and 0.7%.
  • the hydrophilic phase may further comprise additives, pH adjusters, wetting agents, rheological modifiers, such as viscosizing and gelling agents.
  • rheological modifiers such as viscosizing and gelling agents.
  • it may comprise cationic polymers, cellulose derivatives of natural and semisynthetic extraction, silica and derivatives, EDTA, potassium hydrogen phosphate, and sodium hydroxide.
  • Said hydrophilic phase further comprises water.
  • the lipophilic phase of the topical product comprises wetting and emollient agents and a heterogeneous mixture of heavy oils and saturated paraffinic hydrocarbons, such as petrolatum oil.
  • the emollient and wetting agent may be selected from isopropyl myristate and isopropyl palmitate, preferably isopropyl myristate, in a final concentration of 30% to 75%, preferably 40% to 70%.
  • Petrolatum oil is present in a final concentration of 20% to 50%, preferably 25% to 45%, even more preferably 30% to 40%.
  • the lipophilic phase comprises petrolatum oil, isopropyl myristate, squalane, or a mixture thereof, more preferably a mixture thereof.
  • the biphasic topical product of the present invention may be prepared by methods which comprise the mixing of the individual components of each phase, and then the subsequent addition of the lipophilic phase to the hydrophilic phase.
  • a method dedicated in particular to the preparation of the preferred embodiments of the product of the invention has been developed.
  • a second aspect of the present invention therefore comprises a method for preparing a product for topical use, preferably for external topical use.
  • Said method comprises the following steps:
  • Said method preferably comprises the following steps:
  • the two phases form at the time of packaging when the two phases are added at successive times, the hydrophilic phase first and then the lipophilic phase.
  • the main function of the lipophilic phase is to protect the trichloroacetic acid from oxidation, acting as a mechanical barrier against the oxygen present inside the final bottle where the product is portioned.
  • the oxygen in contact with the preparation in the closed bottle would activate the oxidation process with browning (cleavage of the trichloroacetic acid, per se it does not darken, but splits) of the trichloroacetic acid and the relative conversion of the latter into degradation products which are harmful, highly irritating and allergenic to the dermis such as chloroform and formic acid.
  • the lipophilic phase acts as a protection mechanism, thus avoiding contact between the hydrophilic phase, containing the trichloroacetic acid, and the oxygen contained in the bottle even after stirring and mixing between the hydrophilic and lipophilic phase, as a microfilm of lipophilic phase remains constantly above the hydrophilic phase due to density difference and thus permanently protecting the compound from contact with oxygen, and thus preventing the oxidation of trichloroacetic acid, avoiding the conversion thereof into harmful substances for the skin.
  • the two phases may be of two different colors, which choice makes the product even more appealing from the commercial point of view and for the overall pleasantness, for example, yellow for the hydrophilic phase and blue for the lipophilic phase.
  • the second function of the lipophilic phase in addition to that of protecting trichloroacetic acid is to perform a filming, emollient and moisturizing activity on the skin, owing to its composition preferably obtained with: isopropyl-myristate, wetting and moisturizing with natural derivation from nutmeg; squalane with protective function of the skin, due to the ability to regenerate the lipid film which prevents aggression by external agents, and moisturizing, reducing the evaporation of water from the deeper epidermal layers and petrolatum oil which creates a protective film
  • the hydrophilic phase is characterized not only by trichloroacetic acid, but also preferably by an innovative mixture of alpha (tartaric acid, citric acid), beta (salicylic acid) and poly (lactobionic acid) hydroxy acids rich in hydroxyls, selected and dosed advantageously in the present invention, and which perform an additional direct hydration function in addition to the already known exfoliating one.
